What is sympathetic and parasympathetic neural system?give examples
Autonomic nervous system is divided into two subsystems: the parasympathetic nervous system and sympathetic nervous system.
the parasympathetic system is responsible for stimulation of activities that occur when the body is at rest like sexual arousal, salivation, urination, digestion etc. Its action is complementary to the sympathetic nervous system, which is responsible for stimulating activities associated with the fight-or-flight response and constantly active to maintain homeostasis.
